Realistic Vector Sketch for a person to be used for Medal engraving

I'm in search of an experienced artist skilled in creating realistic vector sketches to capture a person's likeness. The sketch will be used for a medal, so the attention to detail and quality are paramount. The illustration itself must be black and white only and the person should be in a front-facing pose with a background details I will provide before we proceed with the project.

- Black and White Only: The final illustration must be monochrome, avoiding any colors or shades.
- Front-Facing Pose: The person in the illustration should be depicted in a front-facing pose, suitable for a medal design.

Ideal Skills and Experience:
- Proficiency in Vector Illustration: Strong experience in creating vector illustrations is a must, particularly in a realistic style.
- Attention to Detail: Ability to capture intricate details and nuances of the person being illustrated.
- Experience in Designing for Awards: Previous work in designing illustrations for medals or awards will be highly beneficial.

I look forward to reviewing your portfolios and discussing how we can proceed with this exciting project.
